Lots of tidying changes, parameter names have changed but hopefully clearer now.
Few more documentation changes still to come Constructing 3D data doesn't work, but this was also true before Einstein2 changes. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinInitialData/IDBrillData/trunk@80 a678b1cf-93e1-4b43-a69d-d43939e66649
